schaefer electrical components Germany schaefer model schaefer price

schaefer electrical component is a photodetector that converts light into current or voltage signals depending on the mode of use. The die typically uses a photosensitive PN junction, which is highly sensitive to changes in light, exhibits unidirectional conductivity, and changes its electrical characteristics with varying light intensity, allowing the current in the circuit to be altered by the intensity of illumination. Photodiodes are also called photoelectric diodes. Photodiodes are similar in structure to semiconductor diodes; their die is a photosensitive PN junction with unidirectional conductivity, so during operation
